Juan Guzmán, a right-handed pitcher from the Dominican Republic, became a vital part of Major League Baseball during the 1990s. Born on October 28, 1966, in Santo Domingo, Guzmán began his professional career when he was signed by the Los Angeles Dodgers as an amateur free agent in 1985. However, it was with the Toronto Blue Jays that he truly found his stride.

Guzmán made his MLB debut with the Blue Jays on June 7, 1991. His rookie season was impressive, as he posted a 10-3 record with a 2.99 ERA, helping Toronto secure a spot in the postseason. His performance earned him a third-place finish in the American League Rookie of the Year voting. Guzmán's fastball and slider combination proved to be effective weapons on the mound, and he quickly became a reliable starter for the team.

The following year, Guzmán continued to excel, playing a crucial role in the Blue Jays' first World Series championship in 1992. He recorded a 16-5 record with a 2.64 ERA during the regular season and was instrumental in the postseason, winning two games in the American League Championship Series against the Oakland Athletics. His efforts helped Toronto capture the title, and he was a key component of the team's success.

In 1993, Guzmán contributed to the Blue Jays' repeat as World Series champions. Although his regular-season performance saw some decline, with a 14-3 record and a 3.99 ERA, he remained a dependable option in the rotation. Guzmán's ability to perform under pressure was evident once again during the playoffs, as he helped Toronto secure back-to-back championships.

Throughout the mid-1990s, Guzmán continued to be a mainstay in the Blue Jays' rotation. He led the American League in ERA in 1996 with a 2.93 mark, despite a modest 11-8 record. Injuries, however, began to take a toll on his performance and availability. Guzmán's time with the Blue Jays came to an end in 1998 when he was traded to the Baltimore Orioles. His stint with the Orioles was short-lived, as he was traded again later that year to the Cincinnati Reds.

Guzmán's tenure with the Reds was brief, and he struggled to regain his previous form. In 1999, he signed with the Tampa Bay Devil Rays, but injuries continued to hamper his effectiveness. After a short stint with the Devil Rays, Guzmán's major league career came to a close.

Over his career, Juan Guzmán compiled a 91-79 record with a 4.08 ERA and 1,243 strikeouts. His time in the majors was marked by moments of brilliance, particularly during the Blue Jays' championship runs in the early 1990s.
